As the title says I am curious about whether the line transposition (eg - 1/3-1/3-1/3 transposition scheme) affects the behavior of fault-induced transients compared to an ideally transposed transmission line.
Is there any literature that has analyzed this topic?
Dear Sir, I refer the general output of extensive studies performed about 50 years ago on the Transient Network Analyzer. The results obtained with a continuously transposed model are close with those obtained by an asymmetrical model with full transposition as you mention. This refers to a generic study. When attempting to reproduce a specific transient recorded in the network the actual transposition scheme (with many other details) should be considered. By the way the 1/6-1/3-1/3-1/6 scheme is preferable since it doesn't affect the physical position of the phase conductor in the stations.
Moreover, the above reported general conclusion applies to a single circuit transmission lines. When the coupling between parallel circuits is present (say two circuits on the same support or in close proximity) the differences of the results obtained by the continuously transposed model and the asymmetric model might be large.
As regard the literature references, I remember that there were some working documents of CIGRE WG groups 13-05 and 33-02 in early seventies. In those days there was also a symposium at UMIST organized by prof. Bickford on transients produced by faults. May be you can find something.
Best regards, Giulio Santagostino
